TAP225K016SCS Equivalent & Substitute Parts

Part Overview

The TAP225K016SCS is a 2.2 µF conformal coated tantalum capacitor rated at 16 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is classified as Active product status with 1,864 units in current inventory. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit applications, particularly when higher voltage ratings or improved ESR characteristics are required for design optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAP225K016SCS are qualified based on the following criteria:

Electrical Compatibility: Capacitance value (2.2 µF) and tolerance (±10%) must remain constant. Voltage rating may be equal or higher, as increased voltage rating provides design margin without affecting circuit function at the original operating voltage.

Mechanical Compatibility: Mounting type (Through Hole), package style (Radial), and physical dimensions must accommodate the same PCB footprint. Lead spacing of 0.098" (2.50mm) is the primary constraint for direct substitution.

Environmental & Compliance: Operating temperature range (-55°C ~ 125°C), conformal coating type, and RoHS3 compliance status must be maintained or exceeded.

Performance Characteristics: ESR values may be equal or lower; lower ESR represents improved performance. Lifetime rating at 85°C must meet or exceed 1000 hours.

Substitute parts are grouped into two categories: voltage-upgraded variants within the same manufacturer (KYOCERA AVX TAP series) and cross-manufacturer equivalents (Vishay Sprague 199D series) that meet identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

KYOCERA AVX TAP Series Upgrades (TAP225K020SCS, TAP225K025SCS): These parts maintain identical mechanical footprint and conformal coating specifications while providing higher voltage ratings. TAP225K020SCS (20 V) offers reduced ESR at 7 Ohm compared to the original 8 Ohm specification. TAP225K025SCS (25 V) provides the lowest ESR at 6 Ohm and highest inventory availability (6,489 units). Both variants are Active status with ROHS3 compliance and are suitable for applications requiring design margin or improved transient response characteristics.

Vishay Sprague 199D Series Cross-Manufacturer Equivalent (199D225X9016A1V1E3): This part matches the original 16 V rating and conformal coating type with equivalent electrical performance. Physical dimensions show minor variations: 0.173" diameter (4.40mm) versus 0.177" (4.50mm), and lead spacing of 0.100" (2.54mm) versus 0.098" (2.50mm). These dimensional differences remain within typical PCB tolerance ranges for radial component footprints. The part is Active status with ROHS3 compliance and 1,800 units in inventory. ESR specification is not provided for this part.

All substitute parts maintain the -55°C to 125°C operating temperature range, 1000-hour lifetime rating at 85°C, and Active product status required for production applications.

Frequently Asked Questions (FAQ)

Q: Can TAP225K020SCS or TAP225K025SCS be used in place of TAP225K016SCS?

A: Yes. Both parts maintain 2.2 µF capacitance, ±10% tolerance, and identical mechanical dimensions (0.177" diameter, 0.276" height, 0.098" lead spacing). The higher voltage ratings (20 V and 25 V respectively) are electrically compatible with 16 V circuit requirements. TAP225K025SCS additionally provides improved ESR performance at 6 Ohm.

Q: What are the dimensional differences with the Vishay Sprague 199D225X9016A1V1E3?

A: The 199D series has a slightly smaller diameter (0.173" versus 0.177") and marginally different lead spacing (0.100" versus 0.098"). Height is comparable (0.280" versus 0.276"). These variations are within standard PCB footprint tolerances for radial through-hole components and do not prevent direct substitution on existing layouts.

Q: Does the Vishay Sprague part provide ESR specifications?

A: ESR is not specified in the available data for 199D225X9016A1V1E3. The original TAP225K016SCS specifies 8 Ohm ESR. If ESR performance is a critical design parameter, the KYOCERA AVX TAP series upgrades (TAP225K020SCS at 7 Ohm or TAP225K025SCS at 6 Ohm) provide documented ESR values.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TAP225K020SCS, TAP225K025SCS, and 199D225X9016A1V1E3 are all ROHS3 compliant, matching the original part specification.

Q: Which substitute part offers the best inventory availability?

A: TAP225K025SCS has the highest current inventory at 6,489 units, compared to 2,100 units for TAP225K020SCS and 1,800 units for the Vishay Sprague equivalent.

Q: Can these parts be used interchangeably on the same PCB design?

A: KYOCERA AVX TAP series parts (TAP225K016SCS, TAP225K020SCS, TAP225K025SCS) share identical mechanical footprints and are directly interchangeable. The Vishay Sprague 199D225X9016A1V1E3 has minor dimensional variations that may require PCB layout verification, though typical radial component tolerances accommodate these differences.
